Question 1

can a pinhole test determine if you have lazy eye or not?

Accepted Answer

Maybe: The pinhole test is a rapid screening technique to check for gross focusing errors in the eyes.  If the vision improves dramatically with a pinhole we at least know the amblyopia isn't too severe.  The only real way to quantify it is to do a refraction with a device called a phoropter which uses real lenses.

Question 2

i have seen a lot of mixed opinions on if pinhole glasses will help one's eyes, but will wearing them do any harm?

Accepted Answer

No harm: Pinhole glasses only allow the image to be projected through the center of your cornea and lens where no refractive error will blur the image.  This does no harm, but also won't help your underlying refractive error.

Question 3

can pinhole glasses help improve eyesight or reduce eye strain?

Accepted Answer

Yes: Pinhole can help sharpen vision, but at the expense of decreasing your field of vision (see straight ahead only with no peripheral).  Eye strain can be reduced by having the proper refractive correction.

Question 4

my optometrist has been unable to correct the vision in my left eye to 20/20, however i can see 20/20 through a pinhole spectacle. regarding higher order aberrations do they ever disappear/resolve or do they tend to get worse with time?

Accepted Answer

: Pin hole is the means to determine if there is uncorrected refractive (eyeglass) needs.  A second opinion might be in order here with your ophthalmologist who could figure out the correct number.  Unless you have had previous injury or surgery for that eye, higher order aberrations are extraordinarily rare.

Question 5

if you have a retinal tear, does the pinhole test not improve blurry vision?

Accepted Answer

: Two separate questions , first if you have a retinal tear it needs to be fixed.  The pinhole test is to see if your blurry vision can be improved with a glasses or contact prescription.

Question 6

if pinhole test improves vision what does this mean?

Accepted Answer

: If cornea or the lens is causing the blurred image, vision will improve with pin hole. It means that you need to go to optometrist and find out your refractive error and get the glasses or contact lenses. Hope it helps.

Question 7

cyl eye test -2.5 means what?

Accepted Answer

Astigmatism: The 'cyl' column in your eye prescription refers to astigmatism.  You can think of astigmatism like warping on the surface of your eye -- like a football shape compared to a basketball shape.  You have 2.5 diopters of astigmatism.

Question 8

how are eye vision test generally scored?

Accepted Answer

Compared to standard: The chart used to test the eye is calibrated for normal vision at 20 feet. The outcome achieved is compared to what a normal eye can see at 20 feet. So if you can only see at 20 feet what a normal eye sees at 40 feet, your vision is considered to be 20/40. This is measured with and without corrective lenses at distance and at near. The vision with correction is considered to show the true vision.

Question 9

what is koh test for eyes?

Accepted Answer

Fungal test: If the doc suspect fungal infection around the skin of the eye then the test can be performed.

Question 10

how can i test eye dominance?

Accepted Answer

Which eye dominant?: This is very important in refractive surgery. Line up one's thumb with both eyes open focusing on a distant target.  Close the right eye and see if it is still aligned with the thumb. If it is you are right eye dominant if not you will notice it aligned when you close the left eye and you are right eye dominant.
